光纤陀螺电路对陀螺温度性能影响的实验研究

Influence of Circuit on Fiber Optic Gyroscope Performance over Temperature

针对干涉式光纤陀螺的电路在环境温度变化时影响陀螺输出的问题,设计了电路部分相关的温度实验,得到陀螺输出与电路温度变化之间的关系.根据陀螺输出和温度变化对陀螺输出进行补偿.结果显示,经补偿的陀螺零偏漂移减小为未补偿时的23%,零偏稳定性提高了7.32倍.

When the circuit of interferometric fiber optic gyroscope（IFOG） is affected by the changing circumstance temperature,the IFOG s bias drifts.To get the relationship between the IFOG output and the temperature change of the circuit,temperature experiment on the circuit portion is designed.Based on the relationship,the IFOG s output is compensated.The results show that the compensated bias drift is twenty-three percent of the uncompensated one,and the bias stability is 7.32 times higher than the original one.
